The headline is actually "Preds head to Stanley Cup Finals." I think that they ran out of space in the headline and someone who doesn't really follow hockey thought that that was acceptable language, since the Preds are heading to one of two "Finals." It's incorrect and sloppy, but I can see how the mistake might occur, and local TV stations are notoriously bad when it comes to reporting hockey (just look at the "Recommended Stories" section at the bottom of the page), so it's certainly not anything unique to Nashville.
